Eating gluten free can be tough while traveling! Eating in Portland though isn't too hard. Lots of the breweries have gluten free beer. I had a really yummy grilled veggie sandwich off the gluten free menu at Deschute's Brewery. They even fry their delicious sweet potato fries in gluten free oil. (I was impressed with the server's knowledge if cross contamination issues and what the restaurant does to avoid problems.) If you are vegetarian the menu is limited, but otherwise there were plenty of things to eat. Just one gf beer, a northwest pale ale, which was described as a mix between pale ale and IPA. I liked it.
